This invention relates ,to improvements in motor vehicle illumination,and has for its `primary object the provision of a novel head .lightassembly, adapted to be carried by the 5 Vfront of a motor' vehicle,'which will serve the purpose of providing and e'lficient w travelpreceding the vehicle, in a ma for-the adequate lillumination of thezonesf'of devoid of glare and danger to approaching 'imitorist and alsoto prov-idefor the ill umi- nation of the zones to the right andlleft of:the vehicle.

W'iththese and other objects in view, as willappear as the descriptionproceeds, the "invention vconsists in the Anovel features ofconstruction, coinbvinations of elements and ax'rangements of partshereinafter to be fully describe'dl and pointed out in the appendedclaim. g g

As shown inthe accompanying drawings, especially in vFigures l to 6,myimproved illumination system comprises a lighting unit 1, consistingof a casing-2 which in this instance is of substantially ellipticalform. rfhe open front of the casing is covered by a removabletransparent lens 3, and aranged within the casing are a plurality ofrefiectors 4. The upper reflector 4** has its principal axis providedwith a light source 5 so arranged as to project the forwardly directedlong range beam 6, indicated in Figures 1 and 2, a considerable distancein advance of the motor vehicle 7 upon which the lamp re is provid edre'fiectors 4b and sLP, having the lprincipa'l',axes thereofarranged todiverge outwardly, as indicated in Figure 5,'to provide for the sidelighting of abling the vehicle,'enthe areas to theyrigl'it and left ofthevehicle to be illuminated'properly and efiectively vehicle Vduringperiods of flectors'lb and l or tint glare is removed and a gre'atlylimproved light produced.
